of being connected by the coil spring 3G with the 4U-shaped )ortion 18of the switch arm. As shown in gs. l and 2, the spring 3G holds theswitch arm in engagement with the stops 19 or 20, depending uponA theposition of the switch.

ln operating the switch, it is only necessary to rock the lever 28 fromthe position shown in Fig. l to that shown in Fig. 2, in order to throwthe switch from the closed to the open position o1' vice versa. As thelever is rocked from oneposition to the other, the spring 36 will heexpanded until the lower end of the lever passes beneath the pivotalpoint of the switch arm at which time the spring will throw the switcharm quickly into the opposite position and into engagement with theStops Il) or 2l) as the case may be, the oflset end portions 24 and 25of the switch blades quickly engaging with or dis-engaging from thecontact clips 5 and T respectively.
